Problems solved by technology

When the drill bit is stuck, if the lock nut pressed on both sides of the friction plate is tightened, the large gear on the output shaft will not rotate under the pressure of the plate-shaped friction plate. At this time, the motor works, and the internal gear of the gearbox will break teeth. On the contrary, when the lock nut pressed on both sides of the friction plate is loosened, the drill bit will slip again. At this time, the motor works, the output shaft does not work, and the hole cannot be drilled.
Imported friction plates are of good quality, but the cost is too high

Abstract

The present invention discloses a concrete drilling machine with friction disk. Its structure includes the following several portions: motor; speed change box connected with motor; said speed change box has three-stage transmission mechanism; friction disk and elastic pressure plate are respectively set on two sides of main gear mounted on the output shaft in said speed change box; edge of the described elastic pressure plate is respectively stuck on outer side face of said friction disk, said outer side face is respectively contacted with rotatable locking nut and bearing inner sleeve fixed on the output shaft; in the inner hole of main gear a shaft sleeve is tightly fixed, the inner hole of the described shaft sleeve is turnably mounted on the optical axis of output shaft.

Description

technical field [0001] The invention relates to a concrete drilling machine for drilling, in particular to a concrete drilling machine with a friction plate which is matched with construction machines and tools and is specially used for drilling reinforced concrete. Background technique [0002] The concrete drilling machine among the construction machinery and tools is an ideal high-efficiency power tool for drilling, cutting, coring and strengthening reinforced concrete in the world. The above-mentioned concrete drilling machine includes a special motor for concrete drilling of construction equipment and a gearbox connected to it. The output shaft of the motor is the input shaft of the gearbox, and the output shaft of the gearbox is connected to the drill bit of the concrete drilling machine. The gearbox of the above-mentioned prior art concrete drilling machine is a two-stage transmission, that is, the small gear on the output shaft of the motor drives the large gear mesh...
